General description of the anti-lock braking system (ABS) (Audi A6 C4)

The anti-lock brake system (ABS) is controlled by an electronic control unit that monitors the status of all system components. If the electronic control unit detects a malfunction, it disables the ABS system and turns on a warning light on the instrument panel.

If the ABS warning light comes on, indicating that a malfunction has been detected, you should contact a specialist for an accurate diagnosis and repair of the ABS.
